The Fascinating Life Cycle of Salmon (3 Minutes Microlearning)

The life cycle of salmon is a fascinating and complex process that spans several years and includes various stages of development. Salmon are anadromous fish, meaning they are born in freshwater, migrate to the ocean to mature, and return to freshwater to spawn. The life cycle begins when adult salmon swim upstream to freshwater rivers or streams to lay their eggs in nests called redds. After hatching, the young salmon, called fry, spend several months in freshwater before migrating to the ocean, where they spend the majority of their adult lives. In the ocean, salmon grow and mature, feeding on small fish and plankton. When it's time to spawn, the adult salmon migrate back to their birthplace, using their sense of smell to locate the same river or stream where they were born. Once they reach freshwater, the adult salmon stop eating and begin to change physically, developing a hooked jaw and a hump on their back. They then lay their eggs, and the life cycle begins again. The fascinating life cycle of salmon is a testament to their remarkable ability to adapt and survive in different environments, making them an important species in both freshwater and marine ecosystems.
